(7) God made the firmament.--This wide open expanse upon earth's surface, supplied by the chemistry of nature--that is, of God--with that marvellous mixture of gases which form atmospheric air, was a primary necessity for man's existence and activity. In each step of the narrative it is ever man that is in view; and even the weight of the superincumbent atmosphere is indispensable for the health and comfort of the human body, and for the keeping of all things in their place on earth. (See Note, Genesis 1:8.) And in this secondary sense it may still rightly be called the firmament.

The waters which were under the firmament . . . the waters which were above the firmament.--While this is a popular description of what we daily see--namely, masses of running water congregated upon earth's surface, and above a cloudland, into which the waters rise and float--it is not contrary to, but in accordance with, science. The atmosphere is the receptacle of the waters evaporated from the earth and ocean, and by means of electrical action it keeps these aqueous particles in a state of repulsion, and forms clouds, which the winds carry in their bosom. So full of thoughtful contrivance and arrangement are the laws by which rain is formed and the earth watered, that they are constantly referred to in the Bible as the chief natural proof of God's wisdom and goodness. (See Acts 14:17.) Moreover, were there not an open expanse next the earth, it would be wrapped in a perpetual mist, unvisited by sunshine. and the result would be such as is described in Genesis 2:5, that man could not exist on earth to till the ground. The use, however, of popular language and ideas is confessedly the method of Holy Scripture, and we must not force upon the writer knowledge which man was to gain for himself. Even if the writer supposed that the rains were poured down from an upper reservoir, it would be no more an argument against his being inspired than St. Mark's expression, "The sun did set" (Mark 1:32), disproves the inspiration of the Gospels. For the attainment of all such knowledge God has provided another way.

Verse 7. - And God made the firmament. How the present atmosphere was evolved from the chaotic mass of waters the Mosaic narrative does not reveal. The primary intention of that record being not to teach science, but to discover religious truth, the thing of paramount importance to be communicated was that the firmament was of God's construction. This, of course, does not prevent us from believing that the elimination of those gases (twenty-one parts of oxygen and seventy-nine of nitrogen, with a small proportion of carbonic acid gas and aqueous vapor) which compose our atmosphere was not effected by natural means; and how far it may have been assisted by the action of the light upon the condensing mass of the globe is a problem in the solution of which science may legitimately take an interest. And divided the waters which were under the firmament from the waters which were above the firmament. The upper waters are not the material of the stars (Delitzsch, Wordsworth), although Jupiter is of the same density as water, and Saturn only half its density; but the waters floating about in the higher spaces of the air. The under waters are not the lower atmospheric vapors, but the oceanic and terrestrial waters. How the waters are collected in the upper reaches of the atmosphere, Scripture, no less than science, explains to be by means of evaporation (Genesis 2:6; Job 36:27; Job 37:16). These latter passages suggest that the clouds are balanced, suspended, upheld by the buoyancy of the air in exact accordance with scientific principles. And it was so. Six times these words occur in the creation record. Sublimely suggestive of the resistless energy of the Divine word, which speaks, and it is done, commands, and it standeth fast, they likewise remind us of the sweet submissiveness of the creature to the all-wise Creator's will, and, perhaps, are designed as well to intimate the fixed and permanent character of those arrangements to which they are attached.

1:6-13 The earth was emptiness, but by a word spoken, it became full of God's riches, and his they are still. Though the use of them is allowed to man, they are from God, and to his service and honour they must be used. The earth, at his command, brings forth grass, herbs, and fruits. God must have the glory of all the benefit we receive from the produce of the earth. If we have, through grace, an interest in Him who is the Fountain, we may rejoice in him when the streams of temporal mercies are dried up.And God made the firmament,.... By a word speaking, commanding it into being, producing it out of the chaos, and spreading it in that vast space between the heaven of heavens and our earth (z),

And divided the waters which were under the firmament from the waters which were above the firmament; the lower part of it, the atmosphere above, which are the clouds full of water, from whence rain descends upon the earth; and which divided between them and those that were left on the earth, and so under it, not yet gathered into one place; as it now does between the clouds of heaven and the waters of the sea. Though Mr. Gregory (a) is of opinion, that an abyss of waters above the most supreme orb is here meant; or a great deep between the heavens and the heaven of heavens, where, as in storehouses, the depth is laid up; and God has his treasures of snow, hail, and rain, and from whence he brought out the waters which drowned the world at the universal deluge. Others suppose the waters above to be the crystalline heaven, which for its clearness resembles water; and which Milton (b) calls the "crystalline ocean",

And it was so: the firmament was accordingly made, and answered this purpose, to divide the waters below it from those above it; or "it was firm" (c), stable and durable; and so it has continued.
